DLPS037F October 2014 – June 2021 DLPC900
Decoupling capacitors must be located as near as possible to the DLPC900 voltage supply pins. Capacitors must not share vias. The DLPC900 power pins can be connected directly to the decoupling capacitor (no via) if the trace is less than 0.03”. Otherwise the component must be tied to the voltage or ground plane through a separate via. All capacitors must be connected to the power planes with trace lengths less than 0.05”. Mount decoupling capacitors connecting to power rail VDDC (1.15-V) using “via on sides” geometry as shown below in Figure 10-6. If “via on the side” is not possible, 1.15-V decoupling capacitors can be mounted using “via at ends” method, providing traces between the vias and decoupling capacitors’ pads be as short and wide (at least 15-mils wide) as possible.
